2. What Goes before the CART? Introducing Classification Trees with Arbor and CODAP

Author

Erickson, Tim and Engel, Joachim

Abstract

This volume is largely about nontraditional data; this paper is about a nontraditional visualization: classification trees. Using trees with data will be new to many students, so rather than beginning with a computer algorithm that produces optimal trees, we suggest that students first construct their own trees, one node at a time, to explore how they work, and how well. This build-it-yourself process is more transparent than using algorithms such as CART; we believe it will help students not only understand the fundamentals of trees, but also better understand tree-building algorithms when they do encounter them. And because classification is an important task in machine learning, a good foundation in trees can prepare students to better understand that emerging and important field. We also describe a free online tool--Arbor--that students can use to do this, and note some implications for instruction.

Abstract

A pandemic poses particular challenges to decision-making because of the need to continuously adapt decisions to rapidly changing evidence and available data. For example, which countermeasures are appropriate at a particular stage of the pandemic? How can the severity of the pandemic be measured? What is the effect of vaccination in the population and which groups should be vaccinated first? The process of decision-making starts with data collection and modeling and continues to the dissemination of results and the subsequent decisions taken. The goal of this paper is to give an overview of this process and to provide recommendations for the different steps from a statistical perspective. In particular, we discuss a range of modeling techniques including mathematical, statistical and decision-analytic models along with their applications in the COVID-19 context. With this overview, we aim to foster the understanding of the goals of these modeling approaches and the specific data requirements that are essential for the interpretation of results and for successful interdisciplinary collaborations. A special focus is on the role played by data in these different models, and we incorporate into the discussion the importance of statistical literacy, and of effective dissemination and communication of findings.

Abstract

James (Jim) Edward Ridgway, a professor in the School of Education at the University of Durham, passed away at the age of 75. He had a background in psychology and made significant contributions to psychometric testing and assessment. Ridgway was known for his sociability and elegant literary style, combining deep academic scholarship with references to other disciplines and historical literary works. He was involved in various projects related to mathematics education and assessment, including the development of classroom resources and performance assessments. Ridgway also worked on projects that aimed to improve statistical literacy and reasoning with evidence, emphasizing the importance of civic statistics in empowering citizens and promoting democracy. He was a prolific researcher and author, serving in various professional capacities and making significant contributions to the field of statistics education. Ridgway's passing is a loss to the community, and he will be remembered for his wisdom, passion, and kindness. [Extracted from the article]

28. Statistical Literacy for Active Citizenship: A Call for Data Science Education

Author

Engel, Joachim

Abstract

Data are abundant, quantitative information about the state of society and the wider world is around us more than ever. Paradoxically, recent trends in the public discourse point towards a post-factual world that seems content to ignore or misrepresent empirical evidence. As statistics educators we are challenged to promote understanding of statistics about society. In order to re-root public debate to be based on facts instead of emotions and to promote evidence-based policy decisions, statistics education needs to embrace two areas widely neglected in secondary and tertiary education: understanding of multivariate phenomena and the thinking with and learning from complex data.

30. Fostering Self-Concept and Interest for Statistics through Specific Learning Environments

Author

Sproesser, Ute, Engel, Joachim, and Kuntze, Sebastian

Abstract

Supporting motivational variables such as self-concept or interest is an important goal of schooling as they relate to learning and achievement. In this study, we investigated whether specific interest and self-concept related to the domains of statistics and mathematics can be fostered through a four-lesson intervention focusing on statistics. Data about these motivational variables and achievement related to statistics were gathered from 503 eighth graders. Our results indicate that students perceived mathematics and statistics differently with respect to their self-concept and interest. Moreover, statistics-related self-concept and interest could be fostered through the domain-specific intervention, whereby a greater increase was found among students with higher prior achievement in the domain of statistics.

45. Data Science in der Lehrerausbildung: Chancen, Herausforderungen und erste Einsichten

Author

Engel, Joachim

Subjects
Informatik, Data Science, Statistik, Technologie, künstliche Intelligenz
Abstract

Data Science, die Wissenschaft des Lernens aus Daten, gilt als Wissenschaft des 21. Jahrhunderts. Die Data Literacy Charta (Schüller et al., 2020) fordert Data Literacy als unverzichtbaren, in allen Bildungsbereichen zu vermittelnden Teil der Allgemeinbildung. Dieser Beitrag plädiert für einen Kurs in Data Science für angehende Lehrkräfte, der über die Vermittlung von grundlegenden Kenntnissen in Statistik und Algorithmen hinausgehend gesellschaftliche Implikationen von automatisierten Entscheidungen thematisiert.
